A child with astigmatism cannot be cured by exercise. It can be corrected by wearing eyeglasses, and the growth of astigmatism can be controlled by practicing good eye habits. Astigmatism in children is usually caused by genetic factors and poor eye habits. For astigmatism caused by hereditary factors, there is no way to prevent or restore it, so it cannot be changed by self-exercise. For astigmatism caused by bad eye habits, once formed can not be restored, but can be controlled by developing good eye habits, such as do not squint to see, do not lie down to see, etc.. For astigmatism that has already formed, the specific degree and axis of astigmatism can be determined through optometry, and then corrected by wearing eyeglasses. Parents are advised to bring their children to regular medical institutions in time and follow the doctor’s instructions for correction.
